Abstract:

In this study， a novel functionalized ionic liquid （［vaim［Phe］） was designed and synthesized using L-phenylalanine as the anion and 1-vinyl-3-aminopropyl imidazole as the cation. A bacterial cellulose-based functional membrane material （BC-CTA@PIL） was then prepared via graft polymerization. The results showed that when the addition amount of ［vaim［Phe］ reached 300 mg， the maximum stress of prepared BC-CTA@PIL3 reached 5.97 MPa， with antibacterial rates of 99.00% and 96.70% against E.coli and S.aureus， respectively， and a hydroxyl radical scavenging rate of up to 63.78%. The results of the strawberry preservation experiments showed that BC-CTA@PIL3 as packaging materials could significantly prolong the shelf life of freshness.
